London commuters may be spared further travel delays as union officials and London Underground managers are set to re-start talks.
News of the meeting, which will be held at the employment resolution organisation Acas, comes ahead of a planned three-day walkout from the Rail, Maritime and Transport union (RMT) on 5 May.
The RMT held a 48-hour strike on Monday 28 April which caused long delays for London commuters using the underground.
The union took the industrial action over plans to close the network's ticket offices, which will result in the loss of 750 jobs.
Transport for London (TfL) has claimed that more than 650 staff have applied for redundancy and stressed that there would be no compulsory redundancies when the ticket offices shut in 2015.
